How long does Marijuana stay in your System?

This question is asked by many different people, and for good reason. Marijuana is the most commonly used and tested for drug in the United States and several other countries as well. Marijuana is also the drug that is more likely to stay in your system for days, weeks, or even an entire month after the last time that you smoke. Therefore, even though marijuana is one of the least harmful drugs out there, it is also the most likely drug to cause you to fail a drug test.When you ask the question “How long does marijuana stay in your system?” you need to take into account the fact that there is no simple answer to this question. Quite simply, it’s argued both that THC never leaves your brain, as well as that there are several different factors which can affect whether or not you test positive for marijuana use.

The speed at which marijuana leaves your body depends both on the speed of your metabolism, as well as on the half life of THC. Unlike most other substances, the half-life of THC can vary quite a bit, depending on who is using it, when it’s used, and several other factors. For example, it’s estimated that THC can have a half life that ranges anywhere from 1-10 days. It’s almost impossible to find out what that half life is, which means that it is very difficult to use it to calculate how long it will take for all of the THC to leave your body.

Not only that, but your metabolism and how much marijuana you smoked will also have an effect on the length of time that it will take you before you can test without testing positive for marijuana use. After all, the half-life is only the length of time that it takes for you to lose half of the THC that is in your system. If you’ve smoked a lot of marijuana, then it will take you longer before the THC in your body drops back below the amount that is detectable by most drug tests.

The most common period of time is anywhere from 3-30 days

For this reason, when you ask “how long does marijuana stay in your system?” you have to realize that it’s very unlikely that you’ll be able to get a usable answer. The most common period of time is anywhere from 3-30 days, depending on your metabolism and the amount of marijuana that you’ve smoked. This is unfortunate, since it means that while most drug tests can only turn up evidence of other drugs if you’ve been taking the drug within a few days of the drug test, marijuana could still be detected in a urine test up to a month after the last time it is used.

Hair tests are even worse, since your body stores THC in the hair follicles. For this reason, the previous answers to “How long does marijuana stay in your system?” are only useful if you’re going to be forced to take a urine test. For the hair test, depending on the amount of hair that the company takes, it’s possible that marijuana could be detected up to three years after the last time that you smoke.

If you’re worried about testing positive for marijuana, then you should definitely invest in some of the great products that will help you to test negative for marijuana use. This is due to the fact that it takes so long for the THC to leave your system that you’ll probably test positive if you do not. If you don’t have an entire month to wait before you need to take the test, then you should definitely think about some other options to keep from testing positive.
